U.S. Inflation Developments

Remarks by

Stanley Fischer

Vice Chairman

Board of Governors of the Federal Reserve System

at

Federal Reserve Bank of Kansas City Economic Symposium

Jackson Hole, Wyoming

August 29, 2015

I am delighted to be here in Jackson Hole in the company of such distinguished

panelists and such a distinguished group of participants.

I will focus my remarks today on forces--domestic and international--that have

been holding down inflation in the United States,1 and some of the consequences of

recent--primarily international--developments.

Although the economy has continued to recover and the labor market is

approaching our maximum employment objective, inflation has been persistently below

2 percent. That has been especially true recently, as the drop in oil prices over the past

year, on the order of about 60 percent, has led directly to lower inflation as it feeds

through to lower prices of gasoline and other energy items. As a result, 12-month

changes in the overall personal consumption expenditure (PCE) price index have recently

been only a little above zero (chart 1).

The past year’s energy price declines ought to be largely a one-off event (chart 2).

That is, while futures markets suggest that the level of oil prices is expected to remain

well below levels seen last summer, markets do not expect oil prices to fall further, so

their influence in holding down inflation should be temporary. But measures of core

inflation, which are intended to help us look through such transitory price movements,

have also been relatively low (return to chart 1). The PCE index excluding food and

energy is up 1.2 percent over the past year. The Dallas Fed’s trimmed mean measure of

the PCE price index is higher, at 1.6 percent, but still somewhat below our 2 percent

Open Market Committee, or in the Federal Reserve System.

objective. Moreover, these measures of core inflation have been persistently below

2 percent throughout the economic recovery. That said, as with total inflation, core

inflation can be somewhat variable, especially at frequencies higher than 12-month

changes. Moreover, note that core inflation does not entirely “exclude” food and energy,

because changes in energy prices affect firms’ costs and so can pass into prices of non-

energy items.

Inflation as measured by the consumer price index (CPI) generally sends the same

broad message as does the PCE price index (chart 3). That similarity should not be

surprising, because the CPI is the most important input used for constructing PCE prices.

On average, CPI inflation tends to run a few tenths higher than PCE inflation, and,

because the CPI has a modestly larger weight on energy prices, fluctuations in the CPI

measure tend to be a bit larger.

Of course, ongoing economic slack is one reason core inflation has been low.

Although the economy has made great progress, we started seven years ago from an

unemployment rate of 10 percent, which guaranteed a lengthy period of high

unemployment. Even so, with inflation expectations apparently stable, we would have

expected the gradual reduction of slack to be associated with less downward price

pressure. All else equal, we might therefore have expected both headline and core

inflation to be moving up more noticeably toward our 2 percent objective. Yet, we have

seen no clear evidence of core inflation moving higher over the past few years. This fact

helps drive home an important point: While much evidence points to at least some

ongoing role for slack in helping to explain movements in inflation, this influence is

typically estimated to be modest in magnitude, and can easily be masked by other

factors.2

In the first instance, as already noted, core inflation can to some extent be

influenced by oil prices. However, a larger effect comes from changes in the exchange

value of the dollar, and the rise in the dollar over the past year is an important reason

inflation has remained low (chart 4). A higher value of the dollar passes through to lower

import prices, which hold down U.S. inflation both because imports make up part of final

consumption, and because lower prices for imported components hold down business

costs more generally. In addition, a rise in the dollar restrains the growth of aggregate

demand and overall economic activity, and so has some effect on inflation through that

more indirect channel.3

To get a sense of the timing and magnitude of these exchange rate effects, chart 5

shows dynamic simulations of a 10 percent real dollar appreciation, based on one of the

domestic inflation--for example, whether measures of foreign resource utilization play an important

independent role. For evidence supporting such global factors, see Claudio Borio and Andrew Filardo

models we maintain at the Federal Reserve.4 The estimated pass-through from import

prices to consumer price inflation occurs relatively quickly, with effects becoming

evident within a quarter and the bulk of the overall effect occurring within one year. By

contrast, the portion of the dollar effects on inflation that work through the channel of

overall economic activity occurs with considerable lags. In the model shown here, the

appreciation has its largest effect on gross domestic product (GDP) growth in the second

year after the shock. Thus, it is plausible to think that the rise in the dollar over the past

year would restrain growth of real GDP through 2016 and perhaps into 2017 as well. The

rise in the dollar since last summer, of about 17 percent in nominal terms, with its

associated declines in non-oil import prices, could plausibly be holding down core

inflation quite noticeably this year.

Commodity prices other than oil are also of relevance for inflation in the United

States. Prices of metals and other industrial commodities, and agricultural products, are

affected to a considerable extent by developments outside the United States, and the

softness we’ve seen in these commodity prices, has in part reflected a slowing of demand

from China and elsewhere. These prices likely have also been a factor in holding down

inflation in the United States.

The dynamics with which all these factors affect inflation depend crucially on the

behavior of inflation expectations. One striking feature of the economic environment is

Paper Series 2005-835 (Washington: Board of Governors of the Federal Reserve System, January),

www.federalreserve.gov/pubs/ifdp/2005/835/ifdp835r.pdf. This model incorporates monetary policy

responses to economic shocks and thus may show smaller effects on real GDP and inflation than other

partial-equilibrium analyses. That said, the SIGMA model is just one of a number of models that the Board

staff regularly consults to inform their analysis of the U.S. economy.

that longer-term inflation expectations in the United States appear to have remained

generally stable since the late 1990s (chart 6). The source of that stability is open to

debate, but the fact that the Fed has kept inflation relatively low and stable for three

decades must be an important part of the explanation. Expectations that are not stable,

but instead follow actual inflation up or down, would allow inflation to drift persistently.

In the recent period, movements in inflation have tended to be transitory. For example,

one might have expected the Great Recession to generate a downward wage-price spiral,

but this did not occur. Thus, the stability of inflation expectations has prevented inflation

from falling further below our objective than occurred, and it has enabled the Federal

Open Market Committee to look through some upward inflation shocks without

compromising price stability.5

We should however be cautious in our assessment that inflation expectations are

remaining stable. One reason is that measures of inflation compensation in the market

for Treasury securities have moved down somewhat since last summer (chart 7). But

these movements can be hard to interpret, as at times they may reflect factors other than

inflation expectations, such as changes in demand for the unparalleled liquidity of

nominal Treasury securities.

In announcing its July interest rate decision, the Federal Open Market Committee

(FOMC) said:

In determining how long to maintain this target range, the

Committee will assess progress--both realized and expected--

toward its objectives of maximum employment and 2 percent

inflation. This assessment will take into account a wide range of

settled precisely at the target inflation rate.

information, including measures of labor market conditions,

indicators of inflation pressures and inflation expectations, and

readings on financial and international developments. The

Committee anticipates that it will be appropriate to raise the target

range for the federal funds rate when it has seen some further

improvement in the labor market and is reasonably confident that

inflation will move back to its 2 percent objective over the medium

term.

Can the Committee be “reasonably confident that inflation will move back to its 2

percent objective over the medium term”? As I have discussed, given the apparent

stability of inflation expectations, there is good reason to believe that inflation will move

higher as the forces holding down inflation dissipate further. While some effects of the

rise in the dollar may be spread over time, some of the effects on inflation are likely

already starting to fade. The same is true for last year’s sharp fall in oil prices, though the

further declines we have seen this summer have yet to fully show through to the

consumer level. And slack in the labor market has continued to diminish, so the

downward pressure on inflation from that channel should be diminishing as well.

In addition, with regard to expectations of inflation, it is possible to consult the

results of the SEP, the Survey of Economic Projections, which FOMC participants

complete shortly before the March, June, September, and December meetings. In the

June SEP, the central tendency of FOMC participants’ projections for core PCE inflation

was 1.3 percent to 1.4 percent this year, 1.6 percent to 1.9 percent next year, and 1.9

percent to 2.0 percent in 2017. There will be a new SEP for the forthcoming September

meeting of the FOMC.

Reflecting all these factors, the Committee has indicated in its post-meeting

statements that it expects inflation to return to 2 percent. With regard to our degree of

confidence in this expectation, we will need to consider all the available information and

assess its implications for the economic outlook before coming to a judgment.

In addition, the July announcement set a condition of requiring “some further

improvement in the labor market.” From May through July, non-farm payroll

employment gains have averaged 235,000 per month. We now await the results of the

August employment survey, which are due to be published on September 4.

Of course, the FOMC’s monetary policy decision is not a mechanical one, based

purely on the set of numbers reported in the payroll survey and in our judgment on the

degree of confidence members of the committee have about future inflation. We are

interested also in aspects of the labor market beyond the simple U-3 measure of

unemployment, including for example the rates of unemployment of older workers and of

those working part-time for economic reasons; we are interested also in the participation

rate. And in the case of the inflation rate we look beyond the rate of increase of PCE

prices and define the concept of the core rate of inflation.

While thinking of different aspects of unemployment, we are concerned mainly

with trying to find the right measure of the difficulties caused to current and potential

participants in the labor force by their unemployment. In the case of the core rate of

inflation, we are mainly looking for a good indicator of future inflation, and for better

indicators than we have at present.

In making our monetary policy decisions, we are interested more in where the

U.S. economy is heading than in knowing whence it has come. That is why we need to

- 8 -

consider the overall state of the U.S. economy as well as the influence of foreign

economies on the U.S. economy as we reach our judgment on whether and how to change

monetary policy. That is why we follow economic developments in the rest of the world

as well as the United States in reaching our interest rate decisions. At this moment, we

are following developments in the Chinese economy and their actual and potential effects

on other economies even more closely than usual.

The Fed has, appropriately, responded to the weak economy and low inflation in

recent years by taking a highly accommodative policy stance. By committing to foster

the movement of inflation toward our 2 percent objective, we are enhancing the

credibility of monetary policy and supporting the continued stability of inflation

expectations. To do what monetary policy can do towards meeting our goals of

maximum employment and price stability, and to ensure that these goals will continue to

be met as we move ahead, we will most likely need to proceed cautiously in normalizing

the stance of monetary policy. For the purpose of meeting our goals, the entire path of

interest rates matters more than the particular timing of the first increase.

With inflation low, we can probably remove accommodation at a gradual pace.

Yet, because monetary policy influences real activity with a substantial lag, we should

not wait until inflation is back to 2 percent to begin tightening. Should we judge at some

point in time that the economy is threatening to overheat, we will have to move

appropriately rapidly to deal with that threat. The same is true should the economy

unexpectedly weaken.

Finally, while I have been talking today about some international influences on

economic conditions in the United States, I am well aware that, when the Federal Reserve

- 9 -

tightens policy, this affects other economies. The Fed’s statutory objectives are defined

in terms of economic goals for the economy of the United States, but I believe that by

meeting those objectives, and so maintaining a stable and strong macroeconomic

environment at home, we will be best serving the global economy as well.6
